Fatented Norm 3, 11914 Application filed Ianuary 4. 1513. Serial No. 740,256.

To all whom it may. concern Be it known that 1:, MAC J. HEALY, of Bradford, in the county of McKean and State of Pennsylvania, have invented certrain new and useful Improvements in Apparatus for Drawing Hollow Glass Articles;

. and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in apparatus for drawing hollow glass articles such as cylinders from which window glass is made, and is designed particularly as an improvement on the construction disclosed in Patent No, 1,008,465, granted to me port the shades and top plate or frame on the breast Wall and'by cables or chains, whereby the plate or frame and shades may be turned out of the tank or adjusted to compensate for differences in the level of glass in the tank. 1

1 h further object is to provide improved means for regulating the temperature at the lower end or the cylinder being drawn;

With these ends in view my invention consists in the parts and combination of parts as will be more fully described and pointed out in the claims.

In the accompanying drawings, Figure l is a view in vertical section through a por tion of a glass melting tank showing my improvements applied thereto; Fig. 2 is a top plan view of the top plate, shades and ring shield, and Fig.3 is a plan view of the ring shield.

1 represents the tank 2 the breast Wall of the latter and 3 the arch or cap provided With .one or'with a plurality of openings 4. My improvements are located Within these openings i, and consist of a top frame or plate 5, side and back shades 6 and a ring 7, all of which parts are made of hollow metal frames suitably braced to prevent undue expansion or bulging of the sides thereof. The top frame or hollow plate his shaped as shown in Fig. 2 and practically closes the opening in the arch in front of the ring shield 7 so as to prevent undue loss of heat at this point. -The rear end of this'frame or plate 5 1S curved to form the front of the drawing opening through which the cylinder is drawn and it together with the sides and back shades form said drawing opening.

The sides and back shades 6 pro lect upv through. the opening in the arch or can 3 the size of the opening" being s-uch'as to pen mit the shades and top plate or frame to be lifted or tilted oi'it of the opening Whenever it may be necessary or desirableto do so:

-The front plate or frame 5. is provided adjacent its outer end with the brackets 8 each of which is engaged by a finger 8 of sleeve 8*. Each sleeve is mounted to move vertically on a threaded rod 9 and is held in proper adjustment thereon oy the nuts 9?. one of which is secured on the rod 9 above the sleeve and the other below it. By proper manipulation of these nuts, the nt'er end of the plate or frame 5 may be adjusted vertically and then looked. The fingers 8 and brackets'8 form hinges on which theplate 5 and shades maybe turned as previously explained. The rods 9 hrs secured to the supports 9 shown in Fig. 1.- The draw ing opening formed by the top plate 5 and shade 6, 1s circular 1n form and slightly larger than the external diameter of ring shield 7 so as to permit the latter to be moved vertically in and through said openmg so as to engage or release the fiostin i a I I 1 Lng o. e ring shield 7 is supported by the links 10 and cable 11, the latter passing over sheaves and carrying counterweights as fully disclosed in my patent previously referred to, and the shades are also supporter? at the rear by the adjustable links 1 2 suspended from a cross bar of the tank and carrying a hook 13 to enter an eye 13 in the upper edge of the back shade.

T he side shades and top plate or frame are rigidly connected, and are hollow, the space or chamber in the top plate communicating with the chamber in the side shades so that the ater may flow freely from one to the other. The ring shield is also hollow, to contain Water, and Water is kept in circulation through these parts by flexible inlet pipes 14 and outlet pipes 14 preferably invention.

coupled to the shades at-the upper edge of the latter, and also to the ring shield, valves 14 being located in the supply pipes for regulating the flow to the parts. It will therefore be seen that the temperature adjacent the drawing point can be regulated by the water supplied to theparts, thus controlling to a certain extent the point at which the glass sets. With this improvement the entire structure within the opening in thearch of the tank is movable and removable, thus permitting it to be tilted outwardly when access is desired to the interior of the tank or removed or tilted outwardly when repairs to same are necessary.

It is evident that many slight changes might be resorted to in the relative arrangement of parts shown and described Without departing from the spirit and scope of my Hence I would have it understood that I do not wish to confine myself to the exact construction and arrangement of parts shown and described, but

Having fully described my invention what I claim as new and desire to secure by Let-' ters-Patent, is

1. Apparatus for drawing glass articles consisting of a tank having an opening in the top thereof, a top plate adjustablyand removably mounted within said opening in a plane below the top of the tank and provided with a drawing opening, side and rear shades carried by said top plate and closing the space between said top plate and the top of the tank and external means supporting said plate and shades.

' 2. Apparatus for drawing glass articles consisting of a tank having an opening therein, a top plate having a drawing opening therein and adjustably and removably mounted Within the o ening in the tank and below the top thereo sides and back shade integral with said plate, the said plate and shades being hollow and water cooled, andexternal means supporting said plate.

3. Apparatus for drawing glass articles consisting of atank having an opening through its top, connected top plate and side and rear shades removably mounted within said opening, the plate having a drawing opening therein and located in a plane below the top of the tank and the shades closing the space between the top of the plate and the top of the tank, and a ring shield adjustably supported by external means within the tank below the top plate.

4:. Apparatus for drawing glass articles consisting of a tank having an opening through'its top, a top plate hinged at its outer end and located within the opening in the tank in a plane below the top of the latter whereby it may be turned upwardly and outwardly from the tank, the said plate being provided with a drawing opening, side and rear shades rigid with the top plate and closing the opening in the tank between the top plate and top of the tank, and :external means supporting the plate and shades Within the tank.

In testimony whereof, I have signed thisspecification in the presence of two subscribing witnesses.
